You will get them all, except for test shots, accidental duplicates, missed-focus, and unrecoverable faulty shots which are deleted during the initial revision (culling).
While we don't cap ourselves, we normally don't "spray and pray" as less experienced photographers may do. We shoot very selectively, either taking our time building up and developing a shot prior to pressing the shutter, or watching an action closely from the ambush, ready to snipe that shot at the right moment. We are after quality, not quantity.
As such, we cannot commit to or target a given number of photos: it will depend on the flow of the session or event. A very rough estimate is 50-100 photos per hour.
